Kernow 1.5.0.9 [beta] available

I've made a new beta version of Kernow available:

• XSLT directory transforms are now multi-threaded, with the size of the thread pool configurable in the options. For systems with multi-core processors and enough available memory this can really improve directory transform time.
• Single File / Standalone transforms now have a "Performance Testing" feature where the transforms are run repeatedly and the average time displayed.
• The panels can now be resized for the XQuery Sandbox tab. The fixed size XQuery Sandbox made it pretty useless before - at least now you can see more than four lines!
  
• Other minor bug fixes

There's loads still to do, but I'm trying to stick to the "release early, release often" policy.
